To all whom it mag concern:

Be it known that ROBERT WALKER RANNIE MACKENZIE and'ERNnsT H. ROBINSON, sub-' jects of the King of Great Britain and Ireland and the Isle of Man, residing, respectively, in Earlsholl, F ife, Scotland, and Stormo'ntfield, Perth, Scotland, MORRIS FORT,

a subject of the King of Great-Britain and Irelandand the Isle of Man, residing in Cromwell Cottage, Almondbank, Perthshire, Scotland, did, in connection with JAMES DAVID LUMSDEN, formerly a subject of the King of Great Britain and Ireland and the Isle of Man, residinv in Huntingtowerfield,

Almondbank, Perths hire, Scotland, but now deceased, during his lifetime, invent I m provements in and Relating to the Beethng and Treatment of Fabrics (for which we 'have filed applicationsin England, Patent ing fabrics, having particular relation to beetling prooesscs.

An important object of our invention is more fully hereinafter. 7.

Other objects and applications of our in-- to provide a method of beetling bleached or unbleached fabrics which are composed'of vegetable fibers. f

Another object of our invention is to provide a treatment for fabrics which permits the beetling of certain fabrics heretofore considered incapable of satisfactory beetling I and which results in a fabric having greatly improved characteristics, all aswill appear vention, as well as the details of the process involved therein, will be apparent from the 1 following description of the nature, the mode 4:5

of operation, and the of our invention.

We have dlSCOVGlGd that particular advantages the effectiveness of a beetling treatment, when applied to, fabrics composed of cotton, linen, or other vegetable fibers, is largely dependent upon the moisture content and distribution of the same and also upon thepresence of small amounts of oily, fatty, waxy, soapy, or res-' inous matter, which may be naturallyin cluded in the fabric or applied during the treatment thereof. For example, one of two similarly bleached cotton fabrics, which failed to respond satisfactorily to a beetling treatment, was found-to contain 0.19% of" waxy and fatty matter; whereas the other piece, which responded well to the beetling treatment, contained only 0.05% of waxy and fattey material. However, after the fabrics were treated, according'to our invention, with a suitable solvent, each responded equally well to the beet-ling treatment and the maximum effect as to firmness and closure of the fabric interstices obtained.

Our invention, therefore, comprises a process, wherein the material under treatment'is first treated to remove the oil, fat, wax and resin content thereof, and thereafter sub jected to a beetling operation.

In the application of our invention to fabrics containing saponifiable oils and waxes, say of the mineral type, which have recentlyentered considerably into the compositionpf sizes applied to linen and cotton yarns before weaving, the solvent treatment is usually carried out on the dry fabric as it is received from the loom or after singeing or at any stage prior to the beetling operation. When the oils and waxes have been removed, the beetling operation may be performed after damping, even before the fab ric is dry.

Our invention is also applicable to brown, grey, green,;half bleached linen, and cotton goods which may be rendered as susceptible to beetling as the correspondingly perfectly.

bleached cloth without resort to the or dinary scouring and bleaching methods. Similar results are obtained with unbleached, half bleached, and bleached fabrics containing various; natural. and extraneous impurities associated with. cellulose, other, than oil,- fat, wax and resin. lhe process constituting our invention, as applied ,to fabrics of the types just specified, comprises a dry cleaning treatment or an extraction treatment; with a volatile solvent,

such, forexample, as benzene, benzine, naphtha, alcohol, ether, or any. other known solvent or solvent mixture capable of dissolving oils, fats, waxes, and resins, which maybe present in a free state or associated with mineral or organic matter. The solvent treatment may be carried out, if desired, in the presence of heat or under modified pressure at any stage in the treatment of the fabric, Where itis necessary for the goods to be mereerized, scoured, dyed, or bleached, the solvent treatment is preferably carried out before the operation just mentioned, to insure good beetling and to permit of, the more effectiveuse of the scouring and bleaching process for the control of the purity or whiteness of the treated fabric.

Our invention is particularly useful in the beetle-finishing of coloredgoods, as, for instance, linen and cotton goods containing dyed or colored threads, which are sometimes required to withstand bleaching before beetling. By reason of the necessity for a milder boiling and scouring treatment for 6 goods of the class herein specified than can be given to ordinary plain goods, in order that the colors shall not be impaired, an inferior white often obtains, and the presence of the fatty or waxy matter results in poor rics, which are firstdyedand subsequently beetled, the solvent treatment is carriedfout while the goods are dry before the scouring and dyeing of the same. If desired, mild scouring treatments may be given subse quent to the solvent treatment to effect such cleansing as may be necessary. l/Vhere fabrics are required to be scoured andblea'ched but not dyed, ordinary scouring treatment. with limeor alkalis may be given-waited a further cleansing action, andit has been 9 found that such scouring treatment is more enective subsequent to the solvent treatment embodied in our invention.

our invention 1s also applicable tosuch materials as mercerized, natural, white and colored or dyed linen and cotton dam asks, dressgoods, upholstery cloths and sheetings, where a good beetledlinishis absolutely es-Y sential. The treatment for goods of the, class just specified may be practicedat any stage ofprocedure after weaving, as, a simple op eration or in conjunction with scouring,

More- 75 bleaching, malting, dyeing, mercerizinga fine ishing or other such known operations as may be required to be performed in order to, obtain certain other desired properties. of: whiteness, purity, color, lustre or finish. Sub:

sequent to the solvent treatment, thebeetling i may be performed rapidly and perfectly at any desired stage on unbleached, mercerized,

dyed, colored, or bleached cloth.

Although we have not described all the possible modifications nd applications of 5 our invention whiclrcould be conceivedfby. one skilled in the art, it is apparentgthat, various changesv and modifications can. be, made therein without departing from the spirit of our invention, and; We desire therefore, that only such limitationsshalhbet imposed thereon, as are indicated in the .ap-,
